Hello, Akmod-nvidia has worked for ages with no issues. Upgrading to F23 has not worked. Removed all nvidia sources and re-installed with no success. make oldconfig HOSTCC scripts/basic/fixdep HOSTCC scripts/basic/bin2c HOSTCC scripts/kconfig/conf.o HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf scripts/kconfig/conf --oldconfig Kconfig # # configuration written to .config # make prepare scripts/kconfig/conf --silentoldconfig Kconfig make[1]: *** No rule to make target 'arch/x86/entry/syscalls/syscall_32.tbl', needed by 'arch/x86/entry/syscalls/../../include/generated/asm/syscalls_32.h'. Stop. arch/x86/Makefile:191: recipe for target 'archheaders' failed make: *** [archheaders] Error 2 I get the same error on two different systems. One with akmods installed and one without, which points to a F23 issue. It may be an issue for others. Robin
